T l M E A LA R M SPECIFICATION forming part of Letters Patent No. 578,059, dated March 2, 1897'.

Application filed July 22, 1895. Serial No. 556,714. (No model.)

HALLAS, a tation of its shaft in one direction and will citizen of the United States, residing at \Va carry the shaft in the opposite direction at terbury, in the county of New Haven and the desired rate of speed when released will State of Connecticut, have invented certain accomplish the purpose of my invention. 55 new and useful Improvements in Time-Ket- In the present instance I have show-n a dial tles; and I do hereby declare the following to graduated from 1 to 10, and of course be a full, clear, and exact description of the use in connection therewith a clock1noveinvention, such as will enable others skilled ment that will produce an entire revolution in the art to whichit appertains to make and of its shaft in ten minutes. 60 use the same. 13 denotes the time-shaft, which is con- My invention has for its object the productrolled by a clock-movement.

The gong is carried by a bracket 15, also by an alarm, if preferred, both move secured to the back of the case, and is soundment and alarm constitutingintegral parts of ed by a striker 16, carried by one arm of a the utensil. bell-crank lever 17, pivoted on a stud 18, ex- 70 IVith this end in view I have devised the tending from the back of the case, a spring novel timekettle of which the following de- 15) acting to throw the striker to the striking scription, in connectionwith the accompanyposition, as will be more fully explained. At ing drawings, is a specification, numbers bethe rear end of the shaft, outside of the case ing used to designate the several parts. and under the gong, is rigidly secured a disk 75 Figure 1 is a section of my novel timeket- 20, having a notch 21, one edge of which is tle, showing the basket in place; Fig. 2, asecstraight and the other inclined, as at 22. tion on the line co m in Fig. 3; Fig. 8, a sec 23 denotes a segment whose periphery cortion on the line y y in Fig. 2; and Fig. & is a responds with the periphery of the disk and detail perspective of one end of the timewhich is provided with a notch 24:, which is So shaft, showing the parts carried thereby de straight on both sides and is adapted to regtached. ister with notch 21. Notches 21 and 24. are 1 denotes a kettle, which may be of any oradapted to be engaged by a lug 32 on the arm dinary or preferred construction and which of the bell-crank lever which does not carry 35 is provided with a handle 2 and an opening3 the striker, the straight rear walls of said 85 in the top, which is covered by a lid 4:, pronotches acting to prevent backward movevided with a handle 5. Upon the under side ment of the pointer, shaft, &c., from the startof the lid at the top is a hook 6, which is ing-point, that is, as in Fig. 1. Upon one side adapted to receive the handle '7 of a basket 8. of notch 2e and in continuation of the wall 40 This basket is ordinarily made of wire, and thereof is a lug 28, the purpose of which will 90 its handle is provided with an eye 9, which presently be explained. The segment oscilpermits its ready attachment to and detachlates freely on a sleeve 25, which is rigidly sement from hook 6. Upon the top of the lid cured to the disk and is provided with a flange I place a case 10, which contains a clock 26, which retains the segment in place. The movement and is provided on the front side oscillation of the segment is limited by pins 5 with a dial 11 and upon the opposite side 29,extendingoutward from thedisk. Aspring with a gong 12. 30, carried by the disk, acts to retain the seg- Ihavenotillustrated or described the clockment in its normal position, that is, the posimovement for the reason that so far as my tion in which notch 2% registers with notch 21. present invention is concerned any clock- The disk, sleeve, and segment are shown as retained in position on the shaft by a thumb nut 31.

The operation is as follows: Suppose that it is required to boil any article of food, for example, eggs, three minutes. The water in the kettle should of course be boiling. The eggs are placed in the basket, the pointer turned toward the rightto the numeral 3, the lid with the basket suspended therefrom is placed in the kettle, and the pointer is re-.

leased. The normal position of the alarm mechanism, that is, the inoperative position, is clearly shown in dotted lines in Fig. 2. hen the pointer is moved toward the right in setting, the mainspring of the clock-movement (not shown) is wound thereby sufficiently to return the shaft to the normal position. The movement of the pointer and shaft in setting of course carries the disk forward also, the movement of the disk being toward the left, as seen in Fig. 2. IVhen the disk commences to move, lug 32 will ride out of notch 21 and up incline The segment also is carried along by the lug until the lug is thrown out of notch 2% in the segment by the incline on the disk. The instant lug S32 is disengaged from notch 24- spring 30 will act to return the segment to its normal position. IVhen the return movement of the shaft and disk takes place, lug 32 instead of riding down incline 22 will be held out of notch 21 by the periphery of the segment until it has reached notch 24; in the segment, which, as already stated, normally registers with notch 21 in the disk. IVhen the lug has reached notch 2%, spring 10 will throw the bell-crank lever from the position shown in dotted lines in Fig. 2 to the position shown in full lines and will throw the striker against the gong, thereby sounding the alarm to indicate that the predetermined time has expired.

Should it be required to boil any article for the full ten minutes for which the timemovement may be set, the pointer would be moved toward the right from the startingpoint entirely around the dial until it registered with the numeral 10. Lug upon the bell-crank lever would be prevented from dropping into notch 21 in the disk by the engagement of lug 32 with lug 28 on the segment. This position of the parts is not shown in the drawings, but it is obvious that lug 32 would rest on the periphery of the segment back of lug 28, thus rendering it impossible for lug to drop into the notch in the disk. Afterthe engagement of the lugs the segment would of course move forward until its movement was stopped by engagement with the pin 29, with which it is not in engagement in Fig. 2.

IVith this device it will be readily understood that a number of the utensils can be employed without danger of confusing the mind as to which one is to be removed from the stove. The indicator or alarm is always present on the kettle when in use, and the pointer or alarm of that particular kettle not only gives notice of the expiration of the time, but also which one of a possible number of kettles is to be removed from the stove or have its basket removed. This is a particular advantage to those persons having charge of the cooking in a hotel or restaurant.

Having thus described my invention, I claim 1. In a utensil of the character described the combination with a case, a dial and a gong, of a ti me-shaft j ournaled in the case and having at one end a pointer and at the other end a disk having a notch 21 inclined on one side, an oscillating segment having a notch 21-, a spring 30 acting on the segment, a bell-crank lever one arm of which carries a striker and the other a lug adapted to register with the notches and a spring 19 acting on the bellcrank lever so that when the time-shaft and. disk are rotated in setting the pointer, the lug will ride up the incline and out of the notches after which spring 30 will return the segment to its normal position and in the return movement the lug will ride on the periphery of the disk until the lug registers with both notches when spring 19 will throw the lug into the notches and the striker against the gong.

2. In a utensil of the character described the combination with a case, a dial and a gong, of a time-shaft journaled in the case and havin g at one end a pointer and at the other end a disk having a notch 21 inclined on one side and on its face pins 20, an oscillating segment whose periphery corresponds with the periphery of the disk and which is provided with a notch2t and a ing 28, a spring 30 acting on the segment whose oscillation is limited by the pins, a bell-crank lever one arm of which carries a striker and the other a lug adapted to register with the notches at the expiration of the time for which the pointer has been set and with lug 28 should the pointer, shaft and disk be turned entirely around in setting and a spring 19 acting on the bell-crank lever substantially as described for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
